VVVAP'ORIZER FOR EXPLOSlVE-ENGINES.

SPEGIFIOATION forming part of Letters Patent No. 726,671, dated April 28, 1903. Application filed December 30,1901. Serial No. 87,705. (No model.)

To '(tZl whom it .may concern.-

Be it known that I, GEORGE A. GEMMER, of Marion,county ofGrant,and State ofIndi-ana, have invented a certain newand uset'ulVaporizer for Gasoleue-Engiues; and I do hereby declare that the following is a full, clear, and exact. description thereof, reference being hadto the accompanying drawings, in which like numerals refer to like parts.

- The object of this invention is to improve the construction and arrangement of the parts of a vaporizer for gasolene and other combustion engines. To that end there is provided improved means for mixing the air and the gasolene-vapor by using a series of screens, the gasolene and air passing through them at a right angle to each other, and also by providing two mixing-chambers,.one..a primary and the other a final mixing-chamber-with aval've for controllingtheair-ports to said chambers, which increases the port to one chamber as -it diminishes the port to the other chamber. I

One novel feature consists of a gas-chain ber intermediate said primary and final mixing-chambers, the outlet from which is controlled by the same valve that controls the outlet from the primary to the final mixing chamber.

There are other novel features in this in.- vention which, together with those above re-T tion of the vaporizer with a portion in verti-i cal section and the cap at the left endand screens removed. Fig. 2 is a horizontal cross-g Fig. 3; is an elevation of the left end of Fig. 1, showsection through the middle of Fig. 1.

ing the device with the end cap and internal parts removed. Fig 4 is an elevation of the cap at the left-hand end of the device. Fig. 5 is a plan view of the screen-mounting as shown in Fig. 6. Fig. 6 is a side elevation of the screens and their mounting. Fig. 7 is an end elevation of the valve that controls the air-ports to the mixing-chambers. Fig. 8 is a plan of said valve and its stem. Fig. 9 is a horizontal section of a part of the device to show a modified construction of valve for controlling the passage'from the primary to the final mixing-chamber.

In detail the construction shown in the drawings to illustrate the general nature of this invention consists of a casing or shell 1, somewhat tubular in form and open at the two opposite ends thereof. At the end marked 2 the vaporizer is attached to the cylinder of the engine to be supplied with combustible fuel. At the opposite end the casing is closed by the removable cap 3. The air-inlet 4 is at the under side of the end adjacent to said cap 3, and an air--chamber 5 is formed separate from the other chambers by a partition 6. Said partition 6 has an airport 7 through it, leading to the primary mixing-chamber 8, and also an air-port 9 through it, leading to the final mixing-chamber 10.

The passage of air front the chamber 5 to the chambers 8 and 10 is controlled by the valve 11, which is substantially semicircular and secured on one end of thestem 12,which is mounted centrally in the cap The valve is pressed in wardagainst the partition 6 by the spiral spring 13 and is controlled or actuated by the crank-like finger 14, whichis secured on the outer end of the stem 12. The end cap 3has a scale on it (shown in Fig. 4) to indicate the proper position of the finger 14 to enable the regulation of the valve 11. The end cap 3 has an inturned annular flange 15, which fits snugly in the casing and has catches 16 to engage pins 17 in the casing, whereby the cap is held in place and rendered readily removable.

The primary mixing-chamberSand the final mixing-chamber 10 are separated by a vertical and longitudinal partition 18, having an opening leading from one chamber to the other which is closed by the conical valve 19. Said valve is mounted on a stem 20, that is longitudinally reciprocable by the cam 40 on the shaft 41, driven by a suitable part of the engine in the casing at one end and in a sleeve 21 from the removable cap 22 at the other end.- It is pressed into a closed position by the spring 23 and is actuated by a moving part of the engine. (Not shown.)

The inlet for gasolene is at the top of the vaporizer, (marked 24.) It is immediately over the outlet-opening 25, (shown in Fig. 2,)

through which the sediment is discharged. Therefore the gasolene drops from the opening 24 upon and through the series of sieves 26. These sieves are made of fine wire and are located adjacent to the port 7 from the air-chamber 5 to the mixing-chamber 8, so that the air-current in passing from chamber 5 to chamber 8 goes through the sieves, and in that manner the gasolene is very thoroughly vaporized.

The sieves 3 are secured at each end to posts 27 in the plate 28, that are secured in the side of the casing, as shown in Fig. 2, the set of sievesextendingintotheopening29. (Shown in Fig. 1.) A plurality of sieves is used to vaporize the gasolene effectually and mix the air therewith.

A gas-chamber 30, supplied through the inlet 31, is for natural gas or other gas when the same is desired to be used with such an engine. This chamber 30 surrounds the conical valve 19, so that when the valve 19 is closed or in its seat it closes the chamber 30, shutting off all passage therefrom to either the chamber 8 or the chamber 10. The one valve 19, therefore, controls this chamber as well as the gasolene-mixing chamber.

The modified form of valve shown in Fig. 9 is actuated in both directions by some means (not shown) connected with the piece 32 of the valve-stem 20. The valve there shown is a hollow slide-valve having rings 33, 34, and 35, that close or open the passageway to the chamber 10 from chamber 8. A casing for said valve is formed by the partition 18, and the extension 36 forms the removable cap 22. The gas-chamber 30 is omitted, showing this modified form.

In operation the air enters the inlet 4: and fills the chamber 5, and such portion of it as may be desired fiows horizontally into the gasolene-mixing chamberSthrough the sieves 26. When valve 19 is actuated by some means pushing against the stem 20, the mixed gas flows into the chamber 10 and from its outlet into the cylinder of the engine. Air enters directly into chamber 10 from chamber 5. The relative quantities of air entering chambers 8 and 10 is regulated by the valve 11, which enables the passage-way into either one of said chambers to be wholly cut off. When one of the passage-ways is diminished, the other is correspondingly enlarged.
